STACKER.

SPECIFICATION forming part of Letters Patent No. 738,390, dated September 8, 1903.

Application filed April 6, 1903. Seria1No.151,360. (N0 model.)

T0 at whom it may concern.-

Be it known that I, FRANK WYATT, a citizen of the United States, residing at Hoxie, in the county of'Sheridan and State of Kansas, have invented certain new and useful Im provements in Stackers, of which the following is a specification.

This invention belongs to the variety of machines for stacking hay, straw, or the like in the field when reaping the harvest. It is customary to gather the grain into sheaves, bundles, or shocks and to convey the latter to a selected spot to be formed in a pile or stack. This machine engages with said bundles or shocks and deposits same upon the stack in the formation of same.

Fora full description of theinvention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a perspective view of a stacker embodying the invention. Fig. 2 is a side elevation thereof. Fig. 3 is a plan section about on the line X X of Fig. 2, the seat and operating-levers being in full.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The frame comprises side bars 1, forwardly 8, to which the animals are. hitched, the

breast-chains 9 being applied tobars 1, near their forward ends, to be connected with the collars of the harness in the usual way. The seat 10 is secured to the rear portion of the reach of the drivers seat.

frame, and the operating-levers are within convenient reach thereof.

Standards 11 are secured at their lower ends to the frame, about midway of its front and rear ends, and are connected at their upper ends by transverse rods 12 and 13 and are braced fore and aft by stays 14 and 15. Direction-pnlleys 16 are applied to the ends of rod 13, and rod 12 forms a pivotal support for the beam or lever 17,carrying fork 18, pivoted thereto. Beam 17 comprises similarly-formed side pieces, each consisting of bar 19 and braces 20 and 21, secured at their outer end to the extremities of bar 19 and upwardly and inwardlyinclined and transversely bored to receive rod 12 at their point of crossing. The side pieces are forwardly diverged in conformity to the inclination of bars 1,the several parts 19 and 21 meeting at their rear ends and provided with eye 22, to which the operating cord or cable 23 is attached, same passing beneath direction-pulley 24, applied cen trally to bar 3, thence forward and attached to drum or spool 25, loosely mounted upon axle 4 and provided with ratchet-wheel 26 for cooperation with pawl 27, whereby said drum is prevented from backward rotation when rotated forward to wind up cord or rope 23 to elevate fork 18. Pawl 27 is connected by rod 28, with hand-lever 29 near the rear end of the machine and within convenient Drum or spool is provided at one end with half-clutch 30 for cooperation with clutch member 31, slidably mounted on axle 4, but connected for rotation therewith. Spring 32 is confined between clutch member 31 andstop 33, secured to axle 4, soas to hold parts 30 and 31, in engagement when it is required to have drum 25 rotate with axle 4, so as to wind up rope or cord 23 to elevate the fork and the load carried thereby. Shipperlever 34, of approximately bell-crank form, is fulcrumed, at

the elbow to cross-bar 2 and has one member IOOv 7 connected at their front ends to the upper end of frame 39 and passed over pulleys l6, thence rearward and downward and attached to operating-lever 4:1, pivoted to the rear portion of the frame and readily accessible from the drivers seat.

In the practical operation of the machine the draft-animals are hitched to the swingletrees 8 and breast-chains 9 in the usual manner, and the machine is advanced with the fork lowered, so as to engage with the shock or bundle, after which lever 36 is operated to throw drum or spool 25 into clutched engagement withaxle4. As the machineisadvanced toward the stack after the load has been received upon the fork spool or drum 25 retates with axle 4 and winds up cord or rope 23, thereby elevating the fork and the load. After the load has reached the required elevation lever 29 is operated to permit pawl 27 to engage with the teeth of ratchet-wheel 26, so as to prevent backward rotation of the spool or drum after the latter has been unclutched from axle 4. Obviously the load may be held in suspension until the frame is properly positioned, after which lever .1 is operated to release fork 18 and permit it to tilt under the weight of the load,which is discharged upon the stack or pile, as will be readilycomprehended. Upon operatinglever 29 spool or drum 25 is released, thereby permitting the fork to descend and assume a next shock or bundle to be deposited upon the stack, the operation being substantially the same as that hereinbefore described.

Having thus described the invention, what is claimed as new is- 1. In a stacker, a beam comprising side pieces rearwardly converged, each side piece comprising a straight bar and oppositely-inclined bars forming braces, a fork pivotally connected to the diverged ends of said side pieces, and operating means connected to the converged elements of the beam,substantially as described.

2. In combination, a frame comprising forwardly-diverged side bars, standards rising from said side bars intermediate of their ends, braces between the upper ends of said standards and the extremities of the side bars, a beam comprising forwardly -diverged side pieces, each comprising a bar and oppositelyinclined brace-bars pivoted at their meeting ends to said standards, a fork pivotally connected to the front ends of said side pieces, a drive-axle, a drum loosely mounted there on, a clutch for throwing said drum into and out of engagement with the axle, an operating-lever for controlling said clutch, a ratchet and pawl for preventing backward rotation of the drum, an operating-lever for controlling the pawl, a cord or rope for controlling the position of the fork, and a lever having said cord or rope connected therewith,'substantially as set forth.

In testimony whereof I have-affixed mysignature in presence of two witnesses.
